Scaffold Fall (KV 144)


What Happened?

A worker fell 15 feet while building a scaffold in the Unit 1 condenser bay. A crew of 4 had started at the beginning of shift to build the scaffold. After breaking for lunch and attending a safety meeting, the crew returned to the job site.

The employee donned his fall protection harness and climbed up the ladder to the elevation where the scaffold platform was being built, and then stepped on to a pan board in order to connect his harness to an anchor point. At this point, he lost his balance and fell before he was able to connect to the anchor point.

The employee struck a horizontal bar of the scaffold, and then landed on his feet on the pan board installed about 8 feet above the floor. The employee was transported off-site for medical evaluation.

Contributing Factors

The pan board was not properly secured to the scaffold allowing it to move when the worker stepped on it.

What Can We Learn?


Plant Procedures require that all scaffold components be positively secured before use.

The crew did not use Effective Communication to discuss where the scaffold erection process stopped before break.


The crew failed to communicate what parts of the scaffold were complete before break. This was a lack of effective communication, or Vague Guidance by the crew.
